An SMTP relay is a type of email server that accepts email messages from one organization and forwards them to another. It can also accept requests to send emails on behalf of other organizations. This article discusses what an SMTP relay is, how it works, and some examples of use cases for when you might want to use one.
What is an SMTP Server & How Does It Work?
An SMTP server is a program that delivers outgoing email. It does not accept incoming emails, but it’s responsible for delivering them to the recipient’s inbox. Email can only be retrieved by POP or IMAP protocol – both of which allow you to retrieve your messages from a mail server remotely.
If you’re looking for a way to send your transactional or marketing emails, then you might be familiar with the term SMTP relay service. This is essentially an email delivery provider that helps manage sending out outgoing mail through SMTP servers such as DuoCircle and networks.
What is an SMTP Relay Service?
The messages that you send need a way to reach its destination. A relay is like an intermediary for your message, which passes it along until its recipient can receive it. SMTP relays are servers or MTA’s with mailboxes who pass on your emails, so they reach their intended recipients without getting stopped by spam filters and other roadblocks in between.
Running email relay servers in the cloud is a great way to ensure that your emails are delivered quicker and with more reliability. The service receives messages from other servers, queues them for delivery, then either delivers on success or generates reports back when there’s trouble delivering mail.
How Does an SMTP Relay Work?
When sending an email, the SMTP relay connects to your computer or mobile device and sends it along with details about where it needs to go next. The relay uses DNS (Domain Name Service) – which is accessed by the domain name on your email address- in order to figure out its final destination. From there, the message may be delivered directly from one of many Mail Transfer Agents operating as servers before hitting that recipient’s inbox.
SMTP Relay Service From a Third Party
The email you send can be more effective when not confined to your organization’s domain. If the mail is coming from there, it may get marked as spam and hurt your reputation on sending marketing emails. A third-party SMTP relay server provider will protect against these consequences of ensuring that deliverability remains good for those who have opted in to receive them.
For a company that relies on email marketing for business, it’s important to find providers with anti-spoofing protection. This will not only keep your clients safe from phishing attacks; but also protect the reputation of your brand when you send emails out.
When Should You Use an SMTP Relay?
You’ve probably sent an email before. SMTP is often used by businesses to send messages in bulk, like marketing emails or transactional notifications like password resets and order receipts. Your favorite software applications might also use it for time-sensitive notices such as paycheck alerts.
Sending mail through an SMTP relay servers is important for the following reasons:
– If a message cannot be sent via your organization’s servers, using an outside server ensures delivery.
– Any messages that are encrypted or digitally signed will pass along to recipients with no issues.
– It might also be helpful if organizations have different domains due to restrictions in sending and receiving from certain networks/environments such as IPv6 only environments where outgoing mails can’t use MX records but must go out by way of A record (IPv4).
– You need a way to send email from hardware like printers, scanners, fax machines and more.
What is the Importance of SMTP Relay?
Email is a pretty straightforward medium for one-on-one correspondence. But managing your own email becomes infinitely more complex in situations when you have an app that sends time sensitive notifications, or sending marketing emails to thousands of recipients at once.
If you’re sending your emails from Gmail or Exchange, don’t expect much. It’s about time to make the move to a reliable email provider that won’t lose touch with its customers and is able to deliver their messages every day without fail.
The SMTP relay service is the key to sending batch sends and automated emails. The trusted third party ensures that you don’t experience deliverability issues as it keeps your mail flowing into inboxes without any issue whatsoever.
The SMTP relay provider is a great service for those who need an alternative to their current email provider. An SMTP server relay acts as the middleman between your computer and your recipient’s inbox, which means you can send emails without worrying about whether they’ll actually reach its intended destination.
This way, you won’t have to worry about dealing with spam filters that are getting more strict by the day because of all the cyber security breaches we’ve seen in recent years.
